摘要

Abstract

Recently

our group produced spin-polarized hydrogen (SPH) atoms at densities of at least 10

-3

from the photodissociation of hydrogen halide molecules with circularly polarized UV light and measured them via magnetization-quantum beats with a pickup coil. These densities are approximately 7 orders of magnitude higher than those produced using conventional methods

opening up new fields of application

such as ultrafast magnetometry

the production of polarized MeV and GeV particle beams

such as electron beams with intensities approximately 10

higher than current sources

and the study of polarized nuclear fusion

for which the reaction cross sections of D-T and D-

He reactions are expected to increase by 50% for fully polarized nuclear spins. We review the production

detection

depolarization mechanisms

and potential applications of high-density SPH.
